C++三个字符串的排序

解题思路:

注意事项:

参考代码:

#include <iostream>

#include <algorithm>

#include <cstring>

#include <cmath>

#include <cstdio>

using namespace std;

int main() {

string a, b, c, temp;

getline(cin, a);'\n';

getline(cin, b);'\n';

getline(cin, c);'\n';

if(a > b){

temp = a;

a = b;

b = temp;

}

if(a > c){

temp = a;

a = c;

c = temp;  

} 

if(b > c){

temp = b;

b = c;

c = temp;

}

printf("%s\n%s\n%s\n",a.c_str(),b.c_str(),c.c_str());

return 0;

}
